@rds100 said: Local laws are sometimes a big pain in the butt. For instance we issue an invoice on paper to everyone with an EU VAT number.

I was told that I need to issue paper invoice for each transaction once I get VAT reg. In Bulgarian. Still figuring on how to modify whmcs and is it even worth it. Luckily no need for VAT regsitration for me yet.

Disclosure: I work for Query Foundry LLC. I own DA International Group Ltd.

Apology for Terror: New free speech offense, used to silence people criticizing the governments for failing to address the real issues driving the radicalization (religious (christian-islamic), political (left-right), etc)

Yea it is related to storage requirements, can't use WHMCS for that.
Also, we DO have a ticket system (OTRS) in background - You just as customer don't see it (unless you look in the headers) - So nothing to worry about :)
